	PR fortran/42783
	* trans-decl.c (add_argument_checking): Do not use the backend
	decl directly to test for the presence of an optional dummy
	argument.  Use gfc_conv_expr_present, remembering to set the
	symbol referenced.

	PR fortran/42772
	* trans-decl.c (gfc_generate_function_code): Small white space
	changes. If 'recurcheckvar' is NULL do not try to reset it.
